Mumbai civic body’s 3D mapping initiative
Subject – Governance
Context – The Brihanmumbai Municipal Corporation (BMC) has completed the first 3D (three-dimensional) mapping of an administrative ward in Mumbai which largely covers Worli area.
Concept –
- The 3D or three-dimensional mapping is the process of preparing a map of the city’s natural areas like water bodies, open spaces, trees and man-made features like roads, buildings and infrastructure facilities in digital format.
- This is the first time that a 3D city model in Mumbai has been prepared.
- 3D model will help at various fronts, like development plan and master plan creation, detection of unauthorised changes, building plan approval system, detailed infrastructure planning of roads, bridges, flyover planning in 3D, analysis and comparison of two alternative designs, urban flooding modelling.
- Currently, the planning takes place in two-dimensional maps and its accurate modeling for infrastructure developments or disaster management is difficult.
- But to meet the demands of cities in the 21st century, it is important that urban bodies are able to visualise their cities in 3D where they can get 360 degree views, undertake simulations and conduct detailed analysis on the data.
- Experts said these three dimensional maps have potential to assist city planners in reaching local climate resilience, economic development and housing goals.
Technologies used –
- For the 3D mapping, Geospatial Technology was used which is a combination of Global Positioning System (GPS), Geographic Information System (GIS) and Remote Sensing (RS).
- Along with this, drones were flown for capturing high definition imagery of the entire area and mobile street imagery vehicles mounted with Light Detection & Ranging (LiDAR) sensors were part of the creation of the virtual model.
- The geospatial technology further helps in analysis, simulation, visualisation and modelling.
